GENERAL DESCRIPTION

WARNING

mum operating pressure of 1716 psi (118 bar) at 2000 psi (138
bar) inlet hydraulic pressure.

INLET PRESSURE TO PUMP MOTOR

Pump ratio is an expression of the relationship between the pump motor area and the
lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is supplied
to the motorofa5:1ratiopump it will develop a maximum of 750 p.s.i. (52bar)fluidpres­sure (at no flow) -- as the fluid control is opened, the flow rate will increase as the motor
cycle rate increases to keep up with the demand.

• The Two--Ball pumps are primarily designed for the pumping of me-

dium viscosity fluids compatible with 400 series stainless steel. The
lower pump is designed for easy priming and the double acting fea­ture is standard in all ARO industrial pumps. Material is delivered to
the pump discharge outlet on both the up and down stroke.

• The motor is connected to the lower pump end by a spacer section.

This allows for lubrication of the upper packing gland and prevents
motor contamination becauseof normal wear and eventual leakage
through the material packing gland. Be sure the solvent cup is ade­quately filled with lubricant to protect the upper packings and insure
longest service life.

PUMP CONNECTION -- UPPER / LOWER

NOTE: All threads are right hand.

1. Lay the pump assembly on a workbench.

2. Remove the top three screws and washers from the three spacer
rods (see figure 1).

3. Pull the hydraulic motor from the lower pump end until motor piston
rod is in the ‘‘down” position and lower pump end rod is in ‘‘up” posi­tion.

4. Remove the three spacer rods by unscrewing the bottom three cap
screws.

5. Remove the cotterpinand unscrew the lower pumpend rod from the
adapter (see figure 2).

TROUBLE SHOOTING

Pump problems can occur in either the Hydraulic Motor Section or the
Lower Pump End Section, use these basic guidelines to help determine
which section is affected.

If the pump will not cycle.

• Be certain to first check for non--pump problems including kinked,

restrictiveor plugged inlet/outlet hose or dispensing device.Depres­surize the pump system and clean out any obstructions in the inlet/
outlet material lines.

• Refer to the motor manual for trouble shooting if the pump does not

cycle and/or hydraulic fluid leaks from the hydraulic motor.

If the pump cycles but does not deliver material.

• Refer to the lower pump end manual for further trouble shooting.

REASSEMBLY

1. Align the pump motor with the lower pump end.

2. Screw the adapter onto the motor piston rod and secure with set
screw.

3. Screw the lower pumprodintothe adapter and secure with the cotter
pin. NOTE: Bend the ends of the pin into the groove of adapter.

4. Reinstall thespacer rods to the lower pump end, securing withthree
cap screws.

5. Bring the motor and lower pump together and retain with the three
screws and washers.
